FAQ

what does deep cycle battery mean

A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity。 In contrast, starter batteries (e。g。 most automotive batteries) are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity。 While a deep-cycle battery can be used as a starting battery, the lower "cranking current" imply that an oversized battery may be required。A deep-cycle battery is designed to discharge between 45% and 75% of its capacity, depending on the manufacturer and the construction of the battery。 Although these batteries can be cycled down to 20% charge, the best lifespan vs cost method is to keep the average cycle at about 45% discharge。There is a direct correlation between the depth of discharge of the battery, and the number of charge and discharge cycles it can perform。
